+// A relatively straight-forward predictive parser.
+// There is no tokenization/lexing stage, the input is parsed
+// in one sweep.
+//
+// To make the parser fast enough to run in the browser, several
+// optimization had to be made:
+//
+// - Matching and slicing on a huge input is often cause of slowdowns.
+// The solution is to chunkify the input into smaller strings.
+// The chunks are stored in the `chunks` var,
+// `j` holds the current chunk index, and `current` holds
+// the index of the current chunk in relation to `input`.
+// This gives us an almost 4x speed-up.
+//
+// - In many cases, we don't need to match individual tokens;
+// for example, if a value doesn't hold any variables, operations
+// or dynamic references, the parser can effectively 'skip' it,
+// treating it as a literal.
+// An example would be '1px solid #000' - which evaluates to itself,
+// we don't need to know what the individual components are.
+// The drawback, of course is that you don't get the benefits of
+// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+// and a smaller speed-up in the code-gen.
+//
+//
+// Token matching is done with the `$` function, which either takes
+// a terminal string or regexp, or a non-terminal function to call.
+// It also takes care of moving all the indices forwards.

+// To make the parser fast enough to run in the browser, several
+// optimization had to be made:
+//
+// - Matching and slicing on a huge input is often cause of slowdowns.
+// The solution is to chunkify the input into smaller strings.
+// The chunks are stored in the `chunks` var,
+// `j` holds the current chunk index, and `current` holds
+// the index of the current chunk in relation to `input`.
+// This gives us an almost 4x speed-up.
+//
+// - In many cases, we don't need to match individual tokens;
+// for example, if a value doesn't hold any variables, operations
+// or dynamic references, the parser can effectively 'skip' it,
+// treating it as a literal.
+// An example would be '1px solid #000' - which evaluates to itself,
+// we don't need to know what the individual components are.
+// The drawback, of course is that you don't get the benefits of
+// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+// and a smaller speed-up in the code-gen.
+//
+//
+// Token matching is done with the `$` function, which either takes
+// a terminal string or regexp, or a non-terminal function to call.
+// It also takes care of moving all the indices forwards.

+// To make the parser fast enough to run in the browser, several
+// optimization had to be made:
+//
+// - Matching and slicing on a huge input is often cause of slowdowns.
+// The solution is to chunkify the input into smaller strings.
+// The chunks are stored in the `chunks` var,
+// `j` holds the current chunk index, and `current` holds
+// the index of the current chunk in relation to `input`.
+// This gives us an almost 4x speed-up.
+//
+// - In many cases, we don't need to match individual tokens;
+// for example, if a value doesn't hold any variables, operations
+// or dynamic references, the parser can effectively 'skip' it,
+// treating it as a literal.
+// An example would be '1px solid #000' - which evaluates to itself,
+// we don't need to know what the individual components are.
+// The drawback, of course is that you don't get the benefits of
+// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+// and a smaller speed-up in the code-gen.
+//
+//
+// Token matching is done with the `$` function, which either takes
+// a terminal string or regexp, or a non-terminal function to call.
+// It also takes care of moving all the indices forwards.

+// A relatively straight-forward predictive parser.
+// There is no tokenization/lexing stage, the input is parsed
+// in one sweep.
+//
+// To make the parser fast enough to run in the browser, several
+// optimization had to be made:
+//
+// - Matching and slicing on a huge input is often cause of slowdowns.
+// The solution is to chunkify the input into smaller strings.
+// The chunks are stored in the `chunks` var,
+// `j` holds the current chunk index, and `current` holds
+// the index of the current chunk in relation to `input`.
+// This gives us an almost 4x speed-up.
+//
+// - In many cases, we don't need to match individual tokens;
+// for example, if a value doesn't hold any variables, operations
+// or dynamic references, the parser can effectively 'skip' it,
+// treating it as a literal.
+// An example would be '1px solid #000' - which evaluates to itself,
+// we don't need to know what the individual components are.
+// The drawback, of course is that you don't get the benefits of
+// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+// and a smaller speed-up in the code-gen.
+//
+//
+// Token matching is done with the `$` function, which either takes
+// a terminal string or regexp, or a non-terminal function to call.
+// It also takes care of moving all the indices forwards.

+// To make the parser fast enough to run in the browser, several
+// optimization had to be made:
+//
+// - Matching and slicing on a huge input is often cause of slowdowns.
+// The solution is to chunkify the input into smaller strings.
+// The chunks are stored in the `chunks` var,
+// `j` holds the current chunk index, and `current` holds
+// the index of the current chunk in relation to `input`.
+// This gives us an almost 4x speed-up.
+//
+// - In many cases, we don't need to match individual tokens;
+// for example, if a value doesn't hold any variables, operations
+// or dynamic references, the parser can effectively 'skip' it,
+// treating it as a literal.
+// An example would be '1px solid #000' - which evaluates to itself,
+// we don't need to know what the individual components are.
+// The drawback, of course is that you don't get the benefits of
+// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+// and a smaller speed-up in the code-gen.
+//
+//
+// Token matching is done with the `$` function, which either takes
+// a terminal string or regexp, or a non-terminal function to call.
+// It also takes care of moving all the indices forwards.

+// To make the parser fast enough to run in the browser, several
+// optimization had to be made:
+//
+// - Matching and slicing on a huge input is often cause of slowdowns.
+// The solution is to chunkify the input into smaller strings.
+// The chunks are stored in the `chunks` var,
+// `j` holds the current chunk index, and `current` holds
+// the index of the current chunk in relation to `input`.
+// This gives us an almost 4x speed-up.
+//
+// - In many cases, we don't need to match individual tokens;
+// for example, if a value doesn't hold any variables, operations
+// or dynamic references, the parser can effectively 'skip' it,
+// treating it as a literal.
+// An example would be '1px solid #000' - which evaluates to itself,
+// we don't need to know what the individual components are.
+// The drawback, of course is that you don't get the benefits of
+// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+// and a smaller speed-up in the code-gen.
+//
+//
+// Token matching is done with the `$` function, which either takes
+// a terminal string or regexp, or a non-terminal function to call.
+// It also takes care of moving all the indices forwards.

+// A relatively straight-forward predictive parser.
+// There is no tokenization/lexing stage, the input is parsed

+//
+// To make the parser fast enough to run in the browser, several
+// optimization had to be made:
+//
+// - Matching and slicing on a huge input is often cause of slowdowns.
+// The solution is to chunkify the input into smaller strings.
+// The chunks are stored in the `chunks` var,
+// `j` holds the current chunk index, and `current` holds
+// the index of the current chunk in relation to `input`.
+// This gives us an almost 4x speed-up.
+//
+// - In many cases, we don't need to match individual tokens;
+// for example, if a value doesn't hold any variables, operations
+// or dynamic references, the parser can effectively 'skip' it,
+// treating it as a literal.
+// An example would be '1px solid #000' - which evaluates to itself,
+// we don't need to know what the individual components are.
+// The drawback, of course is that you don't get the benefits of
+// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+// and a smaller speed-up in the code-gen.
+//
+//
+// Token matching is done with the `$` function, which either takes
+// a terminal string or regexp, or a non-terminal function to call.
+// It also takes care of moving all the indices forwards.
